Battle Commands, Action Commands, and special abilities like Shotlock all have levels in Kingdom Hearts Birth by Sleep and Kingdom Hearts Birth by Sleep Final Mix only. When a command levels up, it becomes more powerful, and can sometimes have special support abilities attached to it. A command can be leveled up by gaining Command Points from defeating enemies in battle, or by playing the Command Board. In Kingdom Hearts: Dream Drop Distance, the commands do not level up and do not combine.

Finish Commands only have one level, but must be mastered before they can be equipped. Instead of gaining experience from obtaining CP, each Finish Command has a specific experience requirement, such as activating a Command Style or slaying Unversed. Furthermore, only Finish Commands linked to the currently equipped Finish Command will accrue experience.

Attack Commands have a Keyblade symbol at the end of their slot, Magic Commands have a Magician hat at the end of their slot, Item Commands have a potion-like symbol at the end of their slot, Friendship Commands have a Hidden Mickey symbol at the end of their slot, Shotlock have a green circle with a three point symbol at the end of their slots, and Defensive Commands have a blue shield with a blue dot in the middle symbol at the end of their slots.

D-Link Commands

Each Dimension Link has its own unique Deck of commands, and while most of these are simply recycled from the normal list of Attack and Magic Commands, the Cinderella, Snow White, and Vanitas D-Link Decks are composed of completely original commands.
